Question

Find the coordinates of the midpoint M
C(3,-5)and D(7,9)

Answer 1

Answer: M(5,2)

Explanation:

C(3,-5) D(7,9) the midpoint M(x,y)=?

x₁=3 x₂=7 y₁=-5 y₂=9

`\displaystyle\\M(x,y)=((3+7)/(2) ,(-5+9)/(2))\\\\M(x,y)= ((10)/(2),(4)/(2))\\\\ M(x,y)=(5,2) \\\\Thus,\ M(5,2)`

Answer 2

(2,7)

Explanation:

we use the midpoint formula:

(3+-5/2 , 7+9/2)

(4/2, 14/2)

(2,7)
